摘要：
A method of constructing an electrophysiology catheter (24) adapted for use in an ostium (11), the catheter having a balloon (80) having a membrane (26) and a flexible circuit electrode assembly (84), The method comprises: providing a flexible circuit (90) having a substrate (34), a first conductive layer (91), and a second conductive layer (92)； removing the first conductive layer (91) to expose a first surface of the substrate (34)； forming the wiring electrode (38) in the second conductive layer (92) with an exclusion zone； forming a first through hole (55) in the substrate (34) to provide a conductive path (48) and forming a second through hole to provide an irrigation opening (35) in alignment with the exclusion zone； forming the contact electrode (33) on the first surface (36) of the substrate (34)； placing conductive material (68) in the first through hole to form the conductive pathway, the conductive pathway extends through the substrate (34) and electrically couples the wiring electrode (38) and the contact electrode (33)； coupling a first conductor (51) and a second conductor (53) to the wiring electrode to form a thermocouple； Fixing the flexible circuit (84) to the membrane (26) with the wiring electrode (38) between the substrate (34) and the membrane (26).Un procedimiento para construir un catéter de electrofisiología (24) adaptado para su uso en un ostium (11), el catéter que tiene un globo (80) que tiene una membrana (26) y un conjunto de electrodo de circuito flexible (84), el procedimiento comprende: proporcionar un circuito flexible (90) que tiene un sustrato (34), una primera capa conductora (91) y una segunda capa conductora (92)； retirar la primera capa conductora (91) para exponer una primera superficie del sustrato (34)； formar el electrodo de cableado (38) en la segunda capa conductora (92) con una zona de exclusión； formar un primer orificio pasante (55) en el sustrato (34) para proporcionar una vía conductora (48) y formar un segundo orif
